Behaviours/ mental acts are aimed at reducing stress/ preventing a dreaded situation/ event

Compulsion causes distress

OCD: Prevalence

General population: 2.5% Szatmari et.al. (1989): 8-10% of AS/

HFA, 5% in control group Other studies show that OCD can

continue into adulthood

OCD: Vulnerability

Psychological differences (ToM, central executive dysfunction, central coherence)

Boredom/ Lack of structure Differences in sensory experiences Misinterpretation of communication Social misunderstandings

Professional Medication CBT Behavioural

treatments

Parents/ Carers Encourage to

communicate feelings

Adjust environment Sensory

awareness Low arousal

Attention Deficit Hyperactivity Disorder (ADHD) Definition Persistent pattern of

inattention/ hyperactivity-impulsivity

Impairment from symptoms must be across two settings

Clear interference with developmentally appropriate functioning

Symptoms Disruptive/ aggressive

behaviour Constantly “on the go”/

fidgeting Disregard for

consequences?! Inability to finish tasks “Silly” mistakes Dislike for activities

requiring mental effort/ organizational demands

ADHD: Prevalence

3-7% in school-aged children Variety of studies: 50%-66% PDDNOS almost always present as

comorbid condition

Ghaziuddin et.al. , 1992

ADHD: Vulnerability

Psychological differences (sequencing, anticipating consequences; what is “finish” and when?)

Sensory Issues Difficulties filtering Need to work things out cognitively (not

“naturally”) Misunderstandings/ misinterpretation

ADHD: Signals

Many “signals” are part of the presentation of ASDs

Where is the “cut-off”?

ADHD: Treatment Options

Professionals Medication

Parents/ Carers Consistent

approaches

Seeking Professional Help

GP – first point of contact, referral CMHT – have an obligation to treat

individuals affected by enduring mental health problems, regardless of ASD diagnosis

Care Manager/ LD Teams – Care co-ordination includes referral to professionals

Private – can be costly; expertise
